HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 324,816, dated August 215, 1885. Application filed August 18, 1884. (No model.)

To aZZ whom it may concern;

Be it known that I, LEDYARD OoLBURN, of Boston, in the county of Suffolk and State of Massachusetts, have invented new Improve ments in HydrocarbouBurners; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent in- Figure 1 a transverse vertical central sec tion; Fig. 2, atop or plan view; Fig. 3, aside View, Fig. 4, a longitudinal central section cutting between the wick-tubes.

This invention relates to an improvement in the burners or devices for burning hydrocarbons, and especially adapted to heating purposes, but also applicable to lighting purposes, the object of the invention being a perfect combustion; and the invention consists in the construction, as hereinafter described, and more particularly recited in the claims.

In illustrating my invention I show the construction as particularly adapted to heating purposes.

A represents the fount, here represented as elliptical in shape, but may be of any desirable shape, according to the use for which the burner is desired. The top of the fount is covered, and longitudinally across the top and at the center the top is raised to form an airchamber, B. Above the inner surface of the top, and at one end'of this passage, is a standpipe, C, which extends upward a short disthrough which air may pass into the interior of the fount to supply the air-chamber B. In the top of the air-chamber the two wick-tubes E F are arranged and fixed substantially as wick-tubes are usually fixed, but so as to leave a space between them, which space, G, forms an air-fiue leading from the air-chamber B below up to the top of the wick-tubes. The cone consists of a base, H, having a central opening to surround the air-chamber, or constructed so as to set down upon the top of the fount over the air-chamber, and as seen in Fig. 1. This base is chambered out upon its I, which is closed,

under side to form a space,

the chamber P, and

and is simply a dead-air space IS a IlOll-COllductor to prevent the heat from the cone being conducted to the lamp-fount. Around this base is a flange. L, to form a support for the chimney M. This chimney for heating purposes may be made from metal or from mica, or any suitable metal; but for lighting purposes it will be made from glass, or may be from mica. The flange L corresponds to the internal shape of the chimney. The cone extends up from the base, and is composed of double walls, a b, and so as to leave a space, d, between said walls. At about the point where the cone begins to contract is a surround ing horizontal flange, N, which corresponds substantially to the internal diameter of the chimney at that point, and which flange,with the base below and the outer wall, I), of the cone with the chimney, forms an air chamber, P, around the cone. Above the flange N the cone is contracted, and so as to form an opening, B, over the wick-tubes, through which the flame will pass. The contracted or dome part of the cone is also formed of double walls, constituting an air-chamber, 6, independent of the air-chamber (2 below, there being a division between the two, as shown. Into the air-chamber d is an opening, f, near the top of from that chamber d is an opening, 9, into the combustionrhamber surrounding the wick-tubes. Above is an opening, h, from the space around the wick-tubes into theair-chamber e in the dome of the cone, and from that chamber 6 is an opening, a, near the opening R, and which leads directly into the chimney.

The chimney itself is provided with apertures opening into the chambers P, as at Z.

The openings into the respective chambers may be small and numerous openings or extended openings.

The operation of the lamp is as follows: The fount may be filled up to the air-chamber B, that is substantially full. The wicks are lighted in the usual manner for lighting such wicks, it being understood that the wicks are provided with the usual adjusting devices. Air enters through the stand-pipe D, thence down to supply the air-chamber B. From this chamber B the air passes up through the air-flue G to the base of the flame between the wicktubes. At the same time air enters the Chillll ber P, and, as indicated by the arrows, passes down through the chamber at, and through the opening 9 into the combustion-chamber. The air thus entering, aportion of it impinges upon the flame at its base. The balance of it enters through the openings it into the air-chamber e in the top of the cone, and thence out into the chimney around the flame tosupply the chimney above the cone with air. The flame heats the cone throughout, making the chambers (Z heating-chambers for the air which passes through them, and also heats the chambers e to a very high degree, which further heats the air passing through them to the chimney. The openings t'lead the airint-o the chimney near' the base of the flame, and thus an abundant supply of air is supplied to the flame, and in a highly-heated state, and so as to produce full and perfect combustion of the hydrocarbon or the gases generated therefrom within the combustion-chamber. At the same time the constant supply of fresh air into the airchamber B and upon the surface of the oil keeps the surface of the oil cool and prevents the generation of gases within the lamp, the inflow of air serving substantially as an insulator between the flame and the lamp. The deadair spaces I, below the cone, serve as an insulator between the cone and fount.

The air-chamber B, with its inlet outside the burner, and the air-flue Gr between the two wick-tubes, may be employed to advantage with cones or deflectors of known construetions.

The cone may be constructed with air-chambers d, dispensing with the airchambers e; but I prefer to employ both the air-chambers d and 6 with their respective openings. The cone, constructed with the air chambers and passages for heating the air, may be employed with the usual arrangement of wick-tubes without the air-chamber B.

I claim- 1. The combination of the fount A, constructed with an airchamber, B, said chamber provided with an opening for the admis sion of air from outside the burner, a pair of wick-tubes leading from the fount through the air-chamber andprovidcd with the usual wickadjusting devices, and an air-flue, G, from the air-chamber B, between the wick-tubes,with a surrounding cone, substantially as described.

2. In a lamp-burner, the cone and the chimney upon it, the cone constructed to form the air-chamber P inside the chimney and outside the combustion chamber, and with the airchamber d, between said chamber P and the combustion-chamber,with openings f from the chamber P into the top of the chamber d, and with openings 9 from the bottom of the chamber d into the combustion-chamber, substantially as described.

The combination of the fount constructed to form an air-chamber, B, and with an inlet to said air-chamber outside the burner, apair of wick-tubes leading from the fount through said air-chamber, a flue, G, leading from said air-chamber upward between the wick-tubes, the cone surrounding said wick-tubes, constructed with the flame-opening R, and with the chamber P outside the combustion-chamber, and also with an air-chamber, d, between said air-chamber P and the combustion-chamber, openings f, leading from said chamber P to the top of the chamber (1, and openings 9 from the bottom of said chamber (1 into the combustion chamber, substantially as described.

4. In a lamp-burner,the base H,constructed to receive and support the chimney, the cone upon said base, constructed to form the chamber P, between said chimney and the combustion-chamber, the chimney constructed with openings leading into said chamber P, an airchamber, 02, between said chamber P and the combustion-chamber, openings f, leading from said chamber P into said chamber d,and openings g, leading from said chamber d into the combustion-chamber, the dome constructed to form chambers c with openings h from the combustion-chamber leading into said chambers e, and openings 1', leading from said chambers 6 into the chimney and around the flameopening B, substantially as described.

5. The combination of a lamp-fount constructed with an air-chamber, B, and an opening thereto outside the burner, wick-tubes E F, leading from the fount through said airchamber, a flue, G, leading from the air-chamber upward between the wicks, a cone surrounding said wick-tubes and forming the combustion-chamber, said cone constructed to form air-chambers P, a chimney upon said cone with openings through it into said airchamber P, the cone also constructed with an air-chamber, d, between said air-chamber P and the combustion-chamber,openings f, lead ing from the air-chamber P into the air-chamber d, openings 9, leading from the air-chamber d into the combustion-chamber, the dome of the cone constructed with the flame-opening R, and also with air-chambers e, and with openings h, leading from the combustionchamber into said air-chambers e, and with openings '5 from said air-chambers into the chimney and around the flame-opening, substantially as described.
